This supplement isn't going to be for everyone, obviously the style and ruleset is going to be a little alienating, but I hope that given the restrictions of the OD&Desque format and horror influences I've made something that can be quite usable.
Also, I wanted to make a quick note on how mental illness is treated in this supplement, since obviously anything that deals with"insanity" is gonna be a little weird. I'm mentally ill, I don't talk about it much but I suffer from Obsessive Compulsive Disorder and Attention Deficit Hyperactivity Disorder, among other symptoms which have yet to be given formal diagnoses. Part of what has drawn me to the King in Yellow and the Cthulhu mythos are the themes of obsession and being driven mad from forbidden knowledge, which to me feels almost relatable and definitely pretty close to home. Madness and insanity are core themes of these works, so if I stripped them out of Lost Carcosa it would be a bit odd. Nevertheless, I feel like works dealing with mental illness often treat the DSM-V like a monster manual rather than actually have tasteful and complex depictions of mental illness. I've tried to tend towards tastefulness here.
I hope you all enjoy this, and get good use out of it! If you want to, feel free to review it on your blog, I'd love to hear your feedback about it!
